Table 2003 / 25-63-50-992-03
(1) RS version
• RS232: PROTOCOL (J3-F) is strapped to PROTOCOL GND (J3-E). Data are received on RS Rx1
(J3-S) and transmitted on RS Tx1 (J3-A). The reference ground is RS GND (J3-C).
• RS422: PROTOCOL (J3-F) and PROTOCOL GND (J3-E) are not strapped. Data are received on RS
Rx1 (J3-S) / RS Rx2 (J3-T) and transmitted on RS Tx1 (J3-A) / RS Tx2 (J3-B).
(2) I1: ELT activation (when grounded).
(3) I3: ELT test or reset (when grounded).
(4) Parity check:
Without parity: strap between J3- P and J3-R.
With odd parity: no strap.
